задача, не равная решению твоих житейских проблем.
Cheap:Anything that involves a nuclear reactor isnt cheap regardless of its size or thermal output, if you want a cheaper means of increasing
underwater endurance you do what everyone else is doing and utilize AIP.
Generally speaking half the price of an SSN is its nuclear power plant.
Article clearly states the following;
those data indicate that the new submarine is very similar to the Project 877 Paltus (Halibut) diesel submarine, but its water displacement is
greater (3950 vs. 3050 tons).
Project 877 Paltus, NATO code "Kilo".
Among other nations, Chianese run Kilos, and it was the Kilo that jumped the Kitty-Hawk.
Classic Kilo weight – 3050, Project 20120 – 3950.
The difference is 900, Is it all just water displacement, or additional reactor and shielding as well?
I’m sure you’ll agree that MODIFING existing Kilo class with a modern version of VAU-6 is a lot cheaper then building a brand new sub.
Small: The reason nuclear subs are larger is a weight issue, any reactor regardless of its size requires substantial shielding with lead and
that makes them bloody heavy, therefore nuke boats have larger hull forms to increase there displacement.
Sounds reasonable, except that is this case the difference is only 900 tons,
Fast: With a miniture nuclear reactor providing minimal thermal output and batteries? A full size nuke would run rings around it. An AIP would
manage the same speeds if not faster.
That opinion is based on what? All we know that the original reactor put out 600kw and that was how long ago?
I’m sure you’ll agree that progress does not stand still, and considering the power output of modern electric motors, fantastic capacities of
modern batteries combined with unknown output of the new reactor should by all reason result in considerably higher speeds then of the original
That’s the point, smaller class subs utilizing NEW technologies resulting in higher speeds.
Quiet,Stealthy: Full size nukes can run just as quiet, by winding back the reactor output you can shut down all the pumps in the primary
coolant loop and utilize natural convection thereby making the reactor plant completely silent. It is doubtful if you could do that with a mini plant
because winding that back wouldnt provide enough power to move the boat. Yes running on batteries is quieter but you can do that on a full size nuke
too by designing a nuke boat with larger battery capacity. The whole point is if you have a reactor on board giving you an unlimited supply of power
you dont need a diesel to augment it
All true, but the point is that the only sub so far to use hybrid nuclear power is the Project 20120 which is still classified.
It is also true that a full size nuke sub can be wound down to minimize its nose output, but you physically can’t make it SMALLER.
Bigger subs use more metal, and no amount of magnetic signature reduction can completely hide it from the entire world of sensors, while smaller subs
simply produce less magnetic signature, which are easier to reduce, thus by DEFAULT providing more stealth.
Point in fact; we are all aware of the Chinese Kilo class jumping the Kitty Hawk.
Very Dangerous: Any boat of any design can be dangerous, that comes down to the crew manning it.
Kitty Hawk. As those guys how they felt when they were in range of that subs torpedoes.
Great Deterrent: Ok, if you say so.
Kitty Hawk again, it’s a perfect example how a small, seemingly outdated sub displayed it’s ability to endanger a carrier.
Force Multiplier: Not even going to dignify this with a response.
Well, I will. Since the concept of a small sub getting through the defenses of a carrier group has been proven by Chinese, it sure makes more sense
for a nation on a limited budget to purchase two or three smaller nuke hybrids rather then a single, big and expensive pure nuke sub.
Having multiple, smaller platforms capable of performing a task that a single big platform can for the same price IS a force multiplier.
I don’t know how much more simple it can get. With ONE big sub a defending force will have to deal with ONE target, with a number of SMALL subs for
the same price the defenders will be forced to deal with MULTIPLE targets.
My question stands, Why the hell would you? What does it achieve? What is the point?
I’m always here to answer the question of inquiring minds, my pleasure.
(shakes head in dismay and exits the room again)
I do hope that you’ll find the patience get to the point of this particular issue.
